High efficiency air filter is generally used as the filter end, so the requirements for high efficiency filters are also the most stringent. High efficiency filters are the most critical level of filter at all levels and require additional "viewing". The most fundamental way to extend the life of an efficient filter is to keep the dust in the prefilter. The replacement of pre-filtration usually does not need to be discontinued, without debugging, so experienced owners will put their attention and money on the prefilters. For the 10,000 and 100,000 clean plants. Prefiltration can be used with F8 filter, which can last up to five years. F8 filters are the most common prefilters in foreign projects and domestic new projects. For chip plant 100, level 10 or higher, the common efficiency level of prefilters is H10, and many new items are selected for HEPA. In the design of clean room air conditioning system in the past, the filter is commonly configured as: effective and efficient. At that time, the life of high efficiency filters was only 1--3 years, and the worst was months. Therefore, the efficiency of the prefilter determines the life span of the end-filter

The nurses are few, the patient is many, is I from July 1984 to attend nursing work till now, has not solved the difficult problem. This is not something that a nurse can solve, but a nurse who needs to be put to the attention of the government. "The nurse management approach" and "the regulations on the nurse, expressly provides for hospital beds and the proportion of nurses is 1-0. 4, but carry out to every department of the hospital, is short of this standard. When I was working in a beachhead hospital, 10 nurses were responsible for more than 100 inpatients, except for outpatient patients.

Can't change the reality, can only change myself, nurse only work hard, to explain to patients' families more, guide them how to observe his condition, make the patient's life care, psychological care, medication nursing, functional exercise, etc., the patient very family cooperation can be achieved, to reach the expected effect of treatment and care, to avoid mistake on accident. Sometimes, nurses have to ask the doctor to help us to work together, even if they watch a office or (later only a nurse to work the night shift, nurses to ward rounds, or treatment and care, no one in the office, someone to come to the office to find doctors and nurses to do, or how someone stole drug treatment), or even please guard escort situation as well. "Aunt, please help me to look after, I go to the ward to give a patient infusion, the catheter, have a bed to call me."

The main reason is frequently lack of concentration... you drive into the fuel station, and you're thinking of things to replace on dinner, or whether you'll be able to your following appointment by the due date, and the next thing you know, you've put several gallons of petrol inside your diesel tank. Another common cause of while using wrong fuel is the fact that newer kinds of diesel cars less complicated quieter plus more powerful that their predecessors. It is very all to easy to forget that you're not driving a petrol fuelled car, and earn what could be an expensive mistake.
